You may already know that the goal of the open source JFXtras Project is to provide pieces that developers often need in their day-to-day work, but that are currently missing from JavaFX 2. There is an application named JFXtras Ensemble that demos those pieces (currently some Controls and Gauges) available in the JFXtras Project. To install and run the app, visit jfxtras.org and click the appropriate native installer link in the Try It! section.
Congratulations and thanks to the contributors to the JFXtras Project, namely Stephen Chin, Dean Iverson, Tom Eugelink, Gerrit Grunwald, Thomas Bolz and Jonathan Giles. Please consider joining the JFXtras Project and helping us create additional useful pieces for JavaFX 2 application development!
